I think you're mixing up things. uncommit and rebase don't have much
to do with each other. Rebase creates new [sets of] revisions based
on some variation of existing revs. uncommit just shifts the head of
the branch to some other existing rev (usually 'earlier', and in
normal usage the previous); you can do almost that with pull, except
uncommit leaves your WT in the same state.
AFAIK, everybody can do essentially what uncommit does. With git,
it's some manipulation of 'reset' (--soft or --merge, maybe?). mtn,
you'd do something like use update to shift your WT basis to the other
rev, and then remove the branch cert from the revs you want to pop
off. hg maybe you just use pull (without -u)?

On the Internet, nobody can hear you scream.
