No plans to support linux, by chance? I couldn't resist installing it on ubuntu12/LV2011, open a few vi's and replace references lvpython.dll --> lvpython.so, but to no avail (would have been pleasantly surprised if it did...)
Passing by, I found this boolean parser on the NI site. It's neat because it works also in linux, but doesn't support variables which is a hindrance for me, because the workaround is to string-substitute variables and parse the formula at each evaluation, which has a performance hit.
