Overhead.. Right now, Emplode's using the error-correcting protocol that they've designed mainly for USB - which tops out around 350k/sec... FTP uses the TCP/IP stack, which tops out around 1mb/sec.. Empeg has stated that they will eventually (possibly?) use the TCP/IP stack when possible with ethernet to achive higher speeds...
