Two names are cumbersome.

Wow, a lot of people didn't read the OP lol. At no point did he mention taking out the two name system.

QFT.

Also, this would be perfect:

How bout they give us one big name and let us use the spacebar?

Although I'd be a little sad that we'd need quotes around some peoples' names in some text commands, but people are trying to move away from text commands. Also, a max of three spaces per name, and cannot have 2+ in a row.
