Free display of NHibernate IList <Point> as a value for a single column

Question

I have this class:

public class MyEntity
{
    public virtual int Id { get; set; }
    public virtual IList<Point> Vectors { get; set; }
}

How can I map Vectorsin Fluent NHibernate to a single column (as a value)? I thought about it:

public class Vectors : ISerializable
{
    public IList<Point> Vectors { get; set; }

    /* Here goes ISerializable implementation */
}

public class MyEntity
{
    public virtual int Id { get; set; }
    public virtual Vectors Vectors { get; set; }
}

Is it possible to map Vectorsas follows, hoping that Fluent NHibernate initializes the class Vectorsas a standard ISerializable?

Or how else could I map IList<Point>to a single column? I think I will have to write serialization / deserialization procedures myself, which is not a problem, I just need to tell FNH to use these procedures.

I assume that I should use IUserTypeor ICompositeUserType, but I do not know how to implement them, and how to inform FNH about cooperation.
