Expect several.

RFC's and probable MLM workarounds notwithstanding, there are 'too many' other 
critters out there that make unexpected assumptions, and the %26 won't allways 
get the job done. Think address books in MUA's as well as MTA's and - worse yet 
- spam filtering engines.

I base that on the experience of a few well-known commercial entities that have 
an '&' in their legal corporate name (I'm ex C&W for one), and have had to use 
alternatives for the web and mail, such as;

candw for 'C&W' (telecoms. Or they were a long time ago, anyway.)

'bbnt', and 'bbt' for BB&T (Branch Banking & Trust, a regional US bank)

..and several others, many in banking, accounting, law, et al.

It could be a kindness to educate the client before they start running into 
limited ability to deliver reliably.

The 'longname' should be enough to keep the identity need satisfied.

HTH,

Bill
