Wow, I guess it was later than I thought.  Yes, I meant to say we are  
currently using a mixture of 1a and 2a.  And that 3a isn't really a  
viable option.

If b is used/allowed, then it makes the most sense to go with 3b, so  
everyone can help with fixes and updates.

I'll wait to see how everyone else feels before moving further on  
this.  I am assuming that no news means everyone agrees and has no  
problems with the current path.

Ya, I've seen a few mentions of it on infra, but not completely sure  
of what the intent is.  They do talk about a shared Continuum on it  
though.  Not sure if we'd want to take advantage of it, now that  
we've got our own :)

So, I'm waiting to hear what others think as far as where and how  
nightlies get published.
