SubEthaEdit turns 2.0: Is that a good thing?

For the most part, SubEthaEdit is just a tidy little editor that runs only on Mac OS X. However, it's claim to fame is the fact that it supports concurrent editing of documents by multiple people. SubEthaEdit is a fascinating tool for collaborative editing things like conference notes or, heaven forbid, source code (i.e., pair programming where you don't have to strain your neck peering over each other's shoulders :-).

In the v1.0 days, the license was basically donation-ware and there was a clear statement in the FAQ that talked about them cleaning up the code to release it as "open source". Alas, in this v2.0 release, the license has gotten more pointedly commercial (with a non-commercial/demo/trial exclusion) and all mention of any open-source take has disappeared. Now, it's their code and they can do what they want with it but I must confess that I feel misled.

To add insult to injury, v2.0 has switched to a completely different protocol (based on BEEP, blech) and there's no interoperability between v1.0 and v2.0. What are they thinking?
