Any Nigerian Based Citrix Techies ?

I've been into Citrix Support for quite a while and i've always wondered about the depth of penetration of Citrix products in corporate Nigeria. If you support Citrix, use it in your workplace, could you kindly share some experience with your Citrix Infrastructure.

I'm basically interested in existing deployments of Metaframe server, Presentation Server, Secure Gateway, Citriix Access Gateway, Password Manager, WANScaler, NetScaler just to mention a few - in Nigeria. If you support it, what has been the benefits and challenges, if you use it, how has it fared with work productivity and what challenges do you face. Are there any support, deployment, maintenance, design/architecture/integration issues you need help with.  I'm keen to link up with the Citrix community in Nigeria - if any. Regards
