First I for BBv2 I already added a "--buildid=ID" option that does that, 
after your post reminded me about the todo. And in case you don't know 
BBv2 is the next version of Boost.Build we are using for the next 
release. For BBv1...

Of course :-)

Try the attached patch to boost-base.jam. Which should let you use the 
--buildid option with BBv1. It's a quick hack in that it doesn't take 
care to clean up the specified ID to make it filename safe. So you'll 
have to be careful what you specify for the ID.
