This is purely for 3-men end-games. There it takes typically 150-200 ms to generate the EGT. For each additional piece this increases by a factor 64, though. So if I would extend the generator to doing 4 pieces, it would already take 10-13 sec to initialize. For 5 pieces it would need 10-15 min, even if the browser would allow you to grab the required amount of memory (1GB).

Of course off-line EGT generators exist, which can be much faster (JavaScript is not the fastest programming language conceivable). E.g. Fairygen. This can do 5-men EGT, definitely for WD+R4 vs WA (although I am not sure if it could do it for totally unsymmetric pieces).
