Please, could you give an actual 20s refuting 20g rb7n Mc7w De2n Cd2n ? It seems to me we get our M to b6 ( 21g Eb5s mb6s Mb7s xxxx ) no matter what Silver plays. Dd5 and Rg5 can't be saved anyway. 20g Eb5s mb6s Ha6e ra7s is another attacking move I like here.

What about:
20g: rb7n Mc7w Cd2n De2n
20s: Dd5n ed4n Dd6e ed5n
21g: Eb5s mb6s Mb7s Rh1n
21s: dc6n ed6w ec6e Mb6e (Capturing our camel)
 
The trouble with occupying b6 with the camel is that it means we are unlikely to get a replacement piece to c7, forcing us to commit the elephant to defence of c6, making it difficult to make threats in the future.

After 20g rb7n Mc7w De2n Cd2n
20s Dd5n ed4n Dd6e ed5n would be a mistake because of
21g Cd3n Rc4w hc5s Eb5e.
E is tied to c6 but can threaten captures to c3, first h and later m.

I think a good refutation to  
20g rb7n Mc7w De2n Cd2n
is
20s Dd5n ed4n de5s de4w.  
Silver threatens the capture in f6 and even if the gold camel occupies b6 with the Elephant pull, there is no capture threat since the c5 square is blockaded.
 
And the trouble with  
20g Eb5s mb6s Ha6e ra7s  
is  
20s rc8w rb7w Hb6n mb5n
, after which the silver camel is out of reach of our elephant, and both our camel and horse are only used to share control of a trap.
 
(Responding to previous post now: )
 
21s de5s Cd4n de4w dd4s seems like a good continuation for silver there, imo.

After 20g rb7n Mc7w Cd2n De2n
20s Dd5n ed4n de5s de4w
there's still
21g Eb5s mb6s Eb4w/s mb5s and maybe get a not-so-good camel hostage for the already pretty much lost dog and rabbit; doesn't amount to that much but neither does anything else.

It was my 2nd proposal ... see my 1st post
 (and aaaa's one post earlier).

 
I should have been clearer. I meant that the b2 rabbit go to a4, not the c4 rabbit. Specifically, what about Rb2->a4 and the either Hg3->f3 or De2->e3 (probably the latter)? The idea would be to sacrifice the dog, but get the enemy camel + elephant occupied around c3, and use this time to advance the g3 horse toward c6 (come what may near g3).

One variant (not deeply analysed):
20g Rb2w Ra2n Ra3n De2n 20s Rc4w hc5s Dd5w ed4n with threat 21s ed5n de5w cd7e ed6n

I don't think this is a problem. Our position is slightly better now that the horse is freed, and on 21g we can move our elephant back to threaten the camel.

I'm concerned that advancing another rabbit will just make it easier for silve to blockade our elephant. Our existing advanced rabbits are causing enough trouble as it is. If we switched wings with the g3 horse silver will have the strongest free piece in the east, and with the h5 rabbit poised to advance it looks like silver could attack faster than we coould.

20s: Rc4w ed4w X X
 
Would lead to a nasty elephant blockade.

Yeah, I missed 20s: Rc4w ed4w X X That does look pretty bad. The position looks pretty resignable, then--at least against "sharpvector."

What was so terribly wrong with the move I suggested? 20g Eb5s hc5w Rc4n Eb4e may not be a great move but it's not like we should resign there.

Only 4 people participated in the poll so it's no big surprise it was a tie... :/
Since we don't have enough time for a re-poll I broke the tie myself and decided on 20g Eb5s mb6s Ha6e ra7s. (I liked the other move a lot more but looking at the result matrix http://civs.cs.cornell.edu/cgi-bin/results.pl?id=E_4ecdb1c95111608a at least to me looks like this one was preferred)
