I working for a company that is keen to purchase remote access
software, and we have settled on buying either RemotelyAnywhere or
pcAnywhere. I need a competitive analysis listing and comparing the
principal features and functionality of each product, to also include
installation, setup, usability, security and pricing. It should also
summarize the advantages/ disadvantages of each and recommend which
one to purchase. I need this information as soon as possible.

Just some free alternatives to consider, since saving the company
money always makes ya look good

1. XP's installed Remote Access utility seems to work pretty well. 

2. The LogMeIn secure remote service provides basic features for free;
the advanced features are pretty affordable.
