we have been using the RegionReady region module to be notified of all scripts
being ready and running (it sends out a message on the configurable region ready
channel). not sure whether that could be extended to the sculpted prim stuff.
one idea i had (being faced by a similar issue as nebadon) was to use that
RegionReady signal (or the event it itself is using) to enable logins.
