Im no techie and could be way off the mark,so bear with me. From an end user point of view it would be nice for them to justtell external parties to email anything to their business email address. LF appliance, with some hooks into Exchange/mail gatewaywould interrogate mail items and if the attachment was larger than the nominated size, would strip it out, send it to the appliance and send the recipient a notification or embed a LFnote/link in the existing email. Obviously wouldnt necessarily be a secure send but would be a nice option.
