Responses From Twitter to Identi.ca

because of the community on twitter (something i'd like to move to identi.ca) i'm am forced to link it to my identi.ca account. my girlfriend and all my friends are on twitter because either (1) they didn't listen to me or (2) all THEIR friends are on twitter. while i can post to twitter, there's no way to get the responses back from twitter to identi.ca, therefor forcing me to actually goto the twitter site (something i don't want them to have the satisfaction of a better hit count). I'd like that some how to be a feature. is that possible? it would help with people wanting to make the switch and still keep conversations going. i want all my twitter posts to say "from identi.ca" but i'm not sure if that's possible at this point. GRR twitter and your influence on the masses, GRR!
