Wikipedia - "The original protocol has a file size limit of 32 MB,  
although this was extended when RFC 2347 introduced option  
negotiation, which was used in RFC 2348 to introduce block-size  
negotiation in 1998 (allowing a maximum of 4 GB and potentially higher  
throughput). If the server and client support block number wraparound,  
file size is essentially unlimited."  I'd like to assume that Cisco  
and/or Apple aren't using the original protocol specifications from  
RFC783 or RFC1350, but based on some other feedback, it seems that one  
or the other may in fact be guilty, but I don't have the means to test  
that theory.

Sadly, CatOS 8.5 doesn't seem to support scp.

I managed to get rsh working on my laptop, which seemed at the time to  
be far easier than trying to figure out why the Sup wouldn't FTP the  
image off my laptop either *sigh*.
