Also you probably shouldn't use scp. rsync and sftp have mostly the same semantics.

    rsync --bwlimit=2OOK bigfile.iso [email protected]:path/in/destination
    sftp -l 200 bigfile.iso [email protected]:path/in/destination

Although it seems that scp is becoming a wrapper around sftp these days:
