The file-view will be available in a soon-to-be-released LimeWire 4.1.0 beta. The functionality you're looking for (hosting a file via LimeWire) is possible, although to allow it to always work it would require editting the HTML file that has the link to the file to be hosted. By default, LimeWire will require a password of sorts (a random number) in the URL to tell LimeWire that access is allowed via browsers -- this number changes every time LimeWire is restarted. We could add an option that tells LimeWire that all browsers can access it, regardless of a password, and then you could host the file without having to change the password in the URL every time you restart LimeWire.
