I just put it down as leading/alt-leading. I'm quite unconvinced that it is worth it for harder climbs; better to just be more organized and spend less time faffing at the belay (see David Coley/Andy Kirkpatrick's recent ebook). Once the climbing gets harder pitches take longer to lead than second and need more gear and the advantages of moving together start to disappear I suspect, while the disadvantages (reduced safety, rope drag) become more and more significant.
I have some friends who did a speed ascent of Wreckers' Slab simulclimbing but I think that was a special case because:
a) the route is a continuous slab so no issues with rope management,
b) the route is technically quite easy and so could be climbed very fast (hence the speed attempt),
c) the route is quite long (120m) so you actually get some simulclimbing in (the first 50m and last 50m are not simulclimbed on 50m ropes).
There are almost no sport routes in the country long enough to simulclimb, and none of them are easy/slabby enough for it to make sense AFAIK. Few non-mountain trad routes are really long enough either, and the mountain routes are often broken and far too winding, or too hard.
Personally I still think simulclimbing (on a full rope length) is only really useful when you haven't quite reached the belay...
