we'd be happy to deal with it

however we have a few lacks, as we mainly focused on common+sane vcs's
(ie svn, hg, git, bzr) there is need for some extra work to get it done
for things like cvs

also there is some lack for commercial vcs's (ie bitkeeper, perforce,
whatever)

actually threading is quite simple if you follow the following rule

__NEVER__ __EVER__ DO GUI THINGS IN THREADS

we use that approach in pida 
(usually multiple background threads for code-analysis, status stuff and
vcs things)

the executable approach is not nice (possible, but ugly),
but a dbus based approach might come in handy (using async method calls)

however there is not yet a dbus fontend for anyvc, as i didn't yet make
one
