No one else encountered this? Really?
The solution I came up with was to send PDF processing to another server
running CF7. That server processes the CFDocument tag and sends back the file.
Here's the custom tag I came up with to hand off and receive the data.
<!---
TAG NAME AND PURPOSE
tag_pdfball by Jordan Roher, CorpDirect Agents, Inc.
Send a ColdFusion file to another server to be processed into a
PDF.
Then store and return the location of said PDF.
