Unfortunately MtGox has growing problems with customer service on such a large scale. Increasing number of smaller exchanges takes over local markets.
I think it is a positive change:

1 The local, national exchange is familiar with local legal system and can give advise on how to run bitcoin business or how to handle taxes.
2 In their interest is to promote the use of Bitcoin in the local community, so they may support bitcoin startups financially.
3 They can lobby for determining the official legal status for crypto-currencies, which I think is very important in current stage of Bitcoin economical development.

To sum it up, GO CAVIRTEX!!
