Alright, here's my 2 cents:
This effect is awesome. As in, this is easily one of the most awesome visual effects of FSO, next to glowmaps and ambient_factor. You guys should very much be commended for everything BP has so far contributed to FSO gameplay--and you haven't even forced us to wait for the release to give it to us.

That said, here's what I think can be improved on:
1. Like everyone's said, shorter trails. Blah blah blah ad naseum.
2. I think this was mentioned a while back, but different effects for different ships and beams. I think the original effect looks a little silly on an Aeolus--but the effect Fury showed in the second pic of his most recent upload looks perfect for cruisers. Corvettes and up--fire away with the original. It looks amazing.
3. The slash effect looks great--if you're not using the original effect (the "burst with debris flying everywhere" effect--it just looks too crowded and messy). The same effect I mentioned above though, would look great on it too.
I honestly haven't played around with the table, and since it's midnight right now, I probably won't till tomorrow. But I'll look around at it and play around. I'll upload some screenshots too.

Wonderful job guys!
