A pretty easy and fast implementation could be based on one of the new
single threaded, event based HTTP servers like LigHTTPD. The property
tree would map nicely to URL space, the data could be stored in memory,
by a simple custom handler module.

This would take care of concurrency issues and be very fast as HTTP is a
simple protocol. Server push could take care of listeners, but obviously
tied properties would have to go. But the latter have been a source of
problems for modelers anyway, since one cannot attach listeners to them.
I wonder if their performance benefit is really worth the hassle.

And it would provide HTTP access to properties for free, allowing to
dump the correspondent code in FG :)
