What I've seen work out the best for online battles is to give more "general orders" than specific turns. Pesgores and Natalya did theirs the best, IMO. Instead of having each player work out how they attack per turn, have them PM to you vaguer, more general orders that you relay to their troops, that will occupy them over the next 3-4 turns. That way, nobody has to really pay attention to stats other than you, although it's just common sense to tell players about larger weapons (whether it's explosive or not etc.), and other "unusual" aspects.
It also helps to have a good camera eye. Follow all standard lego-photography rules (Macro mode, tripod or tripod substitute, good light), but leave at least a few pictures that show the entire field at different angles (top down is a lifesaver). Sometimes with orders, people will MS paint arrows showing which units should go where, and who should attack what.
