Hey Tim,
Since it may take a few seconds to reload a large map, maybe i may discourage from - dunno - sub one minute reloading or suchs. The label, yes, can be as long as you like since it's malloc()'d - of course the longer you make it, the more space you burn and the more expensive it is to aggregate upon (since it's a key field). In theory the only char that you can't use is the default separator, the ',' sign. But i see you stumbled in some issues (both in this email i'm replying to and in the other): let me try to reproduce them at my end and come back to you.
