With SEM (Search Engine Marketing) in mind, "$" makes sense to someone wanting to dominate the index for a set dollar amount (e.g. $1.com, $5.com, $100.com, etc.). Maybe the $10.com store of eCommerce. Generic, but effective. Even if not practical.
The forward-slash was introduced via the Handshake model for resolving their TLDs, I don't mind it at all. We are already used to seeing the "/" in the url bar anyways for a domain name.
We could definitely use anything like the # or the $ for sure, but they require an extra keystroke.. Eric's and MADs suggestions are interesting as they put the character before the DN rather than afterwards, I wonder how that works for browser reading to resolve the DN and whether it would simply things or not.
