Dropping messages is something that should notify you - in the raw protocol this is entirely possible, so it's just something that needs to be added to the client.
The problem of adding files is something that it would be nice to solve, I think in general the IRC servers themselves wouldn't want to potentially sacrifice the ability to handle text whilst being overloaded with attachments. It feels like something that could be solved with a third party server and a client that supports it, with a short-ish TTL to keep the server freed up. Receiving side it would simply be a case of opening a link or deciding if the content can be displayed inline.
I quite like not being available when I'm offline. I don't want to logon to have a quadrillion messages to read back through - most out of date and don't concern me. We have email for this kind of thing.
