Even that would be quite difficult to consolidate properly for businesses.

This type of "budgeting aid" could be implemented entirely client-side and transparently with respect to the Taler protocols. Users configure their wallets to set certain amounts aside for certain categories and indicate the category to associate with each transaction. The wallet rejects the transaction (and offers access to revise the user's budget to permit the transaction) if the funds allotted to that category would be insufficient within the user's budget.

No other entity need even be able to see the user's categories or budget outline; the "restriction" is entirely in the user's wallet and can be effectively overridden if the user so chooses. Businesses would receive only the standard tokens, with no indication that token X was budgeted for use with them. The "soft binding" use case is entirely client-side, requiring only some additional metadata to preserve the budgeting information when synchronizing wallets.
