Hi Chaps,
I think this might be a better solution,
www.popsapp.com
Its something that I have developed with some friends, we had a system written in house at my viz studio but have spent the last 7 months redeveloping it so that anyone can use it. Still in Beta stage but you can use it to manage arch viz projects and collaborate with other POPS users, upload, download and track files and create a custom ftp area for your clients to upload and download work.
Totally geared up for our industry, in the workflow section you can create custom items and there are presets for Arch Viz stills and animations.
The POPS Viewer is coming soon where you can review images and videos online with you client thus removing the need for emailing attachments.
Would be great to hear what you think,
Rich
