Connection of a drupal sit to a SOA Interface

Hi,

I just want to ask if my strategy makes sense before I do a lot of work and it's not usable. I newer developed a drupal module and am really stressed on a current project to get it work.

What I have:
I've got fully configured Drupal website with Access control.

What I want:
I want to create pages with PHP code inside which connect to the remote SOA interface. I'll build a table outside drupal where the drupal-users are assosiated with the users-id's of the remote system.
Then when someone access a page containing PHP Code inside, this page gets which Drupal-id is assosiated with the remote id.. Take the remote id and gets the content from the remote server and displays as page content.

Make dis sense? Are there better ways? I know, it would be the best way to code a custom Drupal module to do this job, but I don't have the time now and will do this in the future...

What are you opinions about my strategy?

Greets and best regards,
Andy
