Are "proof-of-concept" apps allowed in the App Store? My company deals with a specific technology and we're looking to submit a limited functionality proof-of-concept app to the App Store as a sort of advertisement of our experience and capabilities. Is an app like this likely to be rejected?

Edit: my original question above sounds a little subjective and opinion based, so to clarify: I'm looking for case history or documentation from apple that clarifies this scenario.
There are a great many apps which offer very little in terms of functionality, and essentially advertise a company and accessories (such as the Jabra and Plantronics apps) and some which just display information about select services of the company.

There are also many apps which require specific infrastructures to be in place for an organisation to even use the app which offer no functionality for the average user, such as Good for Enterprise, or Excitor DME. 

As long as it complies with the submission guidelines, there's no reason Apple would reject it.
