Gmail+Writely+Spreadsheets+?... A Perfect World?

So today I made good use of the GMail Suggestion Form today. I think it's great that they list the commonly requested features to save themselves time (and someone making a feature request). However, the feature I was submitting is so glaring and obvious that I can't believe it hasn't become one of their top requests!

Integrate Gmail with Writely, Google Spreadsheets, and Picasa Web Albums.

This seems like an obvious step (or is it just me?). When you have an attachment at the bottom of your email, Google gives you just two options: "View As HTML" and "Download." Isn't it an obvious choice for RTF or DOC files to "Open With Writely?" Isn't it an obvious choice for XLS files to "Open With GSpreadsheets?"

One of the reasons to have Writely and GoogleSpreadsheets is to give the user a web-interface to edit their files (especially if they don't have the software to open the files on their computer). But right now, I have to download the DOC file to my computer, log in to Writely, upload the file to my Writely account, and then begin editing it.

I understand that Gmail is still a beta product, and Writely and GoogleSpreadsheets are both beta products as well. This, however, is a natural step (I think) for these applications to make. In fact, ideally all of these Google programs would be saved and read from an online GoogleHardDrive... but I'm getting ahead of myself.

I'd also like to mention that I was trying to find a way to modify Gmail (with a plugin or something similar) so that it would have these features. But I was unable to find a way for Writely to open files from the web! (Is uploading the only option?) If that's the case, Writely needs to be updated to have this feature!
