Advantages:
- See previous slide...
Disadvantages:
- Lack of access from browser
- No links from email & Web pages, etc.
- Does not leverage deployed HTTP proxies etc. — risk we'll reinvent cacheing, etc.
- Won't leverage emerging Web developments (Semantic Web, AJAX XMLHttpRequest, etc.)
- How will crawlers, etc. know which resources to access using HTTP GET, and which using WS Transfer GET?
