can you use SecurID with rancid?

Hi Terry,

Thanks for the note.  Was just showing your media system web page to
someone this afternoon.

All good points, but where am I left if I want to protect my network
gear with OTPs and still run rancid?  It seems they are mutually 
incompatible.  I can create a single instance of a reusable password to be
used for rancid logins, but that doesn't improve the situation.

So what do you do?
