Hoping this is generally the right place for this question, and that it hasn't already been addressed on the mailing list...
I tend to write mulch tracks on my home desktop computer and perform them on my partner's bootcamped MacBook. Setting aside the legality of the issue for a moment, with Mulch 1.0 it was easy to install on either machine with the same license key.
With Mulch 2.0 it looks like there's a handshake process which (presumably?) means the license key is unique to that machine. Does this mean I would need to purchase two licenses?
