The idea here is I wanted to make a single PrC that can advance two casting classes at once, but something that is better than the Mystic Theruge and similar classes. I got to thinking about the Ultimate Magus, and the "caster level trick" you can pull to keep one class at near full ability while still gaining casting at a moderate rate in a second class. I decided to embrace the trick and base a new PrC around it.
Now, in addition to advancing casting, I wanted to advance the class features as well. As part of the house rules I've been working on (see my sig), I've been rewriting and adding classes that grant class features at each level. As a result, you have to really think about PrCing out of one of those classes. So, this class advances both (although not at the full rate. See the table below).
The idea is that you qualify for the class at 5th level, so you could wrap it up at 15th level. At that point, you would be casting as a 13th level caster in your primary class (with 14th level class features) and you would cast as a 9th level caster in your secondary class (with 8th level class features).
Note: I consider your caster level (for purposes of spell effects) to be equal to your character level at all times. Also, I have re-tooled the casting advancement of all the "9-level" classes to grant new spell levels on the odd levels and not the even levels. So, a 9th level caster in any of these classes would have 5th level spells.

Class Features:Weapon and Armor Proficiencies: A Dual Caster does not gain any weapon or armor proficiencies.
Class Features/Spellcasting: To qualify to be a Dual Caster, you must be able to cast spells from two different classes. When you take your first level of Dual Caster, select one of these classes to be your primary class and the other to be your secondary class. If you have more than two casting classes, pick two of them (one primary and one secondary). Once this choice is made, it cannot be changed.
Every level except 5th level, you gain the class features of your primary class as if you had gained another level in the class itself. This includes spellcasting abilities, such as spells known and spells per day. Every level except for 3rd and 8th, you gain the advance the class features and spellcasting of your secondary class as if you had gained another level in the class itself.
If both classes grant the ability to have a familiar, you may only have one familiar at a time. Use the higher level class to determine the familiar's abilities. The same restriction applies to animal companions.
