there's certainly no doubt that in the short term the US economy will have a effect on revenue. This is clearly apparent by the fact that TZI didn't hit revenue target due to economic conditions in US.

I haven't been on the TZL train for long, but my understanding is that a lot of the original trials and therefore sales were US based. As TZL continues to expand its global reach with more and more trials/implementation of products/services outside of the US then there will be less reliance on the US. By no means am I suggesting the US wont be important, after all it is still the worlds largest economy, but US economic conditions will have less affect on overall revenue if TZL has successfully expanded globally.
