I don't suppose you want to write up an example that does mesh extension/projection? Feel free to say no, as this is mostly a greedy request on my part (the more neat things people can see examples of, the less they have to ask the mailing lists about), but it might also be useful to you to have that feature running in our regression tests. --- Roy ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
