Have Campaigns Reached Their Limits?

[Discovery]

Each SE has a campaign limit
For those new to PPC, think of the campaign as the top level of a directory under which you would create related sub campaigns.

Campaign > Accountants
Adgroup > CPA
Adgroup > Auditing

One of the strategies for a national advertiser with mulitple services is to be able to control their campaigns and sub campaigns at a geo targeted (state) level. You would use Geo targeting settings to filter down to the state level and keywords to further refine potential ad impressions down to the state/city/zip code level.

So you would like to set up a PPC account like this:

Campaign > California
Adgroup > CPA
Adgroup > CFP
Adgroup > Tax Auditing

Campaign > Texas
Adgroup > CPA
Adgroup > CFP
Adgroup > Tax Auditing

Not only can the advertiser uniquely control the message, but as business expands or retracts from a particular state, or adds/removes a service offering for a particular state the affected campaigns can be toggled off and on with incredible accuracy.

Unfortunately, Search Engines only allow a limited number of campaigns!
20 for Yahoo
25 for Google
25 for MSN (Need confirmation)

So a State driven account structure will not work if you plan to cover more than 25 states!

Have others run into this problem?
Have you worked out a solid solution?

An alphabetized campaign doesn't fit, either.

My solution is to bug the CS reps at the engines till they raise my campaign limit.
