Unfortunately, probably not.  How do they know it was company letterhead?  
Had they ever seen the company's letterhead before?  How do they know I 
didn't just create that LOA and letterhead in OpenOffice?

Trouble is, how do you/they know if both the space and ASN have been

The listed contact may not be who ARIN [or other local RIR] thinks it is.

They really don't.  Thus far, when space is assigned, the RIRs have no way 
to later authenticate that an organization using the space is the same one 
that they assigned it to.

As for the current state of BGP authentication/sanity checking, I can say 
2 of my 4 upstreams take whatever I put in the routing registry.  The 
other two require an email be sent requesting prefix filter updates.  I 
was just told by one, that they'll accept whatever I request, only 
questioning it if someone complains to them about it.  The other, I 
haven't asked, but I assume they work similarly.  On the bright side, all 
of them are at least filtering.
