Thanks! This definitely makes for (continued) happy modelling =)

Thanks a lot for all the replies/checks thus far. This is really encouraging. I wouldn't mind if some final tweaking/adjustments might need to be done with the official toolset if there isn't 100% compatibility with BleST. I was just getting a bit worried that the majority of development would have to be migrated over. Thankfully it seems that this wont be the case.

@Artfunkel
From your preliminary investigation, do you foresee anything for the user in terms of Blender usage that might need to be changed? Or is it really just technical details of how BleST is implemented? There was mention by Valve a while back that Workshop submissions should no longer include custom particle effects for the time-being as that system is being overhauled in S2. Would it be possible for you to shed some light on how this affects BleST?

Will Blender + Blender Source Tools still be compatible (and, with regards to the latter, continue to be developed/updated) come the full release of Source 2? Or will model development have to be done with the Source 2 tools?

I'm a huge fan of Blender + Blender Source Tools and my main interest lies in Dota 2 and some personal ventures I have planned once Source 2 is released as a standalone engine. I would much rather prefer to continue with the majority of development in Blender.
