What does bitkeeper moving away from free mean for me?

I'm sorry if I'm asking a really stupid question, but after reading the news
articles and press releases, I still don't exactly know what's going on.

I have a good general understanding that Bitmover is strategically ending
development of the current free version of bitkeeper, and that its being
'cycled out'.

I currently have two open source projects hosted on bkbits.  In addition to
being open source, these projects are completely non-commercial in nature,
they are being used to conduct academic research for telescopes and
computational biology.  I have trained a mathematician who refused to use
CVS or any other kind of versioning system to use Bitkeeper due to its
amazing power-to-simplicity ratio.  He's even  successfully pushed his own
changes to a code we were working on up to bkbits.

If I understand correctly, in the future we will be given a client that will
allow free pull/clone access to bkbits/other repositories, but the ability
to create changesets and commit them will be available only to a
professional version.

So assuming I do have two projects that will continue to be developed in the
next 4 years during the remainder of my term as a graduate student, what are
my options?  

I'd also like to express my appreciation for such a great product, you guys
make version control fun.

Best Wishes,
