It might be so, but I think is more a question of how this or that 
group of people think. Unix guys thinks "text protocol", others are
prone to think "binary protocol", not because it is a proven
performance issue, but because they are used to it, and they don't
have the big/little endian thing or differing floating point formats
to care about.

Ok, I'll try liblo first, if that is to slow, I'll implement it
myself.
